FENCER,
do not take this in an offensive tone, because it isn't intended as one, merely it's to inform.
There's no such thing as a tanto griptilian, the other griptilian blade style is what's called a "Sheepsfoot" blade.
In order to understand what good examples of tanto knives are, I suggest you take a look at any Chisel Ground Tanto Emerson (CQC7B, SPECWAR B, Raven B, Blackbird B, etc.) or a Spyderco Lum Tanto, this should illustrate the diffeerences.
Please note i'm not trying to belittle you with semantics, I just want to help you out, since a storeowner might get pretty confused if you ask for a "Tanto Griptilian".
Ok now that the education is over, it's time for my opinion:
for most everyday cutting tasks a tip is important, one of the key aspects of the sheepsfoot blade is it has extremely little tip, and even that tends not be very sharp - the goal of the sheepsfoot is provide as much slicing belly as is possibly available, the sheepsfoot also makes a fitting blade style for "rescue" knives, since you don't have to worry about the point poking someone you might be trying to help - so for everyday use I have a hard time recommending a sheepsfoot blade.
However, i've heard the complaint that because of the design of the drop point griptilian, deep cutting is virtually impossible - examining the blade, I find this to probably be a legitimate complaint... granted, most EDC use involves shallow cutting, but keep this in mind.
Personally, if *I* was getting a Griptilian (and I think I will be sometime next year), i'd most likely go for the sheepsfoot for the following reasons:
#1 never actually had a sheepsfoot knife before, I think it'd be cool to try.
#2 the sheepsfoot is the "original" blade design for the griptilian, the drop point seems and acts alot more like some kind of afterthought
#3 the sheepsfoot blade seems more like it can handle the deep cutting the drop point can't... in my mind this is kind of important, but bear in mind, that I've got more than one knife, if I had to get one griptilian to do it all, i'd prolly have to go for the drop point.
